One thing to always check – does your computational region contain data you are analysing? Try to run `g.region rast=immagine` before running i.atcorr. Māris. trešd., 2022. g. 26. janv., plkst. 18:13 — lietotājs rakstīja: > > Dear all, > > I am having troubles in processing a Sentinel-2 image

[GRASS-user] NULL values as output of i.atcorr

2022-01-26 Thread ilaria.ferrando87
Dear all, I am having troubles in processing a Sentinel-2 image with i.atcorr. The command I use is the following: i.atcorr -r -input=immagine@mapset range=0,1 parameters=C:\...\22giugno2020_b4.txt output=immagine_atcorr rescale=0,1 and I obtain this output: wavelength less than 0.25
